Description

Technical Field

[0001] The utility model belongs to the technical field of PVC plastic processing, and particularly relates to a stirring device for PVC plastic additives. Background Technique

[0002] At present, during the processing of PVC plastics, additives need to be added to change the properties of PVC plastics, improve the quality of PVC plastics, and accelerate the production efficiency.

[0003] The existing stirring device for PVC plastic additives consists of a stirring barrel and a stirrer. By adding various additives into the stirring barrel and continuously stirring them with the stirrer, various additives are mixed with PVC plastics. However, it does not have an intermittent feeding function. When adding additives, the staff will put all the additives into the stirring barrel, resulting in uneven mixing of the additives. The additives are usually in powder form. When a large amount of additives are mixed with PVC plastics at the same time, the additives are prone to caking, further affecting the uniformity of the mixing of the additives and PVC plastics, and it takes a lot of time to stir and mix them, reducing the production efficiency of PVC plastics.

[0004] Therefore, we provide a stirring device for PVC plastic additives to solve the above problems. Summary of the Utility Model
